As an example, they added 2 cupboard sections in the kitchen which could've been great, except they didn't extend the counter top, so they were using laminate flooring planks to cover them that they had just placed on-top, not even clicked together.

The kitchen and 2 bathrooms have linoleum, I am assuming you would upgrade those too in the cost I gave for estimated repairs.

Frank is looking at granite/SS appliances, designer kitchen and baths, all hardwood floors and great closets space.I will lower the prices by at least few hundred dollars unless you have that qualify of units!

I was told that the estimated cost to repair my building would be around $30k, which would cover carpentry such as doors, flooring, updating the kitchen, windows, and drywall.

@Ryan CannedyBathroom and Kitchens sell (and rent) homes.I don't think this will necessarily increase your rent, but will likely result in finding a tenant faster.

We've only once replaced a hall bath, and only once replace a kitchen.  

Kitchen/Appliances?

All the properties have new tile, bathrooms, kitchens, SS appliances, granite, redone floors, new paint inside and out, windows, new water heaters and HVAC systems in each unit.  

I was looking more closely at the pictures on zillow (which I should've done before) and I noticed that the only full bathroom in the house seems to be off of the kitchen!

Cost of white oval bathroom sink & cutout was $75 each (kitchen sink is $150)Calculating the 3 in (I think that is the size) backsplash that goes around the permiter.
